Hi,
From the jailhouse design, the Private Per-CPU data should be not
accessed by other CPUs except the current CPU. But from the code[1]
and my test, it is not. For example, the CPU1 can access the CPU0's
private data, because hv_paging_structs already map it, and the
per-cpu page table will link the hv_paging_structs. is this a bug？ I
think the Private Per-CPU data should be not accessed by other CPUs
except the self CPU.
[1]: err = paging_create(&hv_paging_structs,
paging_hvirt2phys(&hypervisor_header),
system_config->hypervisor_memory.size,
(unsigned long)&hypervisor_header,
PAGE_DEFAULT_FLAGS,
PAGING_NON_COHERENT | PAGING_HUGE);
